In what anemia the color index is increased?

A color index greater than 1, when correctly determined, is usually regarded as the most constant and characteristic blood finding in pernicious anemia. The great variation in hemoglobin readings in different laboratories, however, makes the color index a very uncertain diagnostic measure.

What does B12 deficiency look like on CBC?

In patients who are deficient in B12, the CBC would show anemia, which manifests as a decrease in both hemoglobin and hematocrit. In addition, the mean corpuscular volume (MCV), which measures the size of red blood cells, would be increased to a level greater than 100.

What does B12 deficiency do to red blood cells?

You need B12 to make red blood cells, which carry oxygen through your body. Not having enough B12 can lead to anemia, which means your body does not have enough red blood cells to do the job. This can make you feel weak and tired.

Does vitamin B12 increase white blood cells?

In the present study, B12 supplementation did not affect white blood cells as well as lymphocytes subpopulations (number and percentage) in the control group (both after 30 and 90 days). A 30-day period of B12 addition in the protein-deficient group reduced the negative effect of malnutrition.

What is the color index of blood?

The color index, taken as the ratio of the percentage of hemoglobin (compared to “normal”) to the red blood cell count (compared to “normal”) has been a useful clinical figure in differentiating iron deficiency from other types of anemia.

What is the Colour index?

colour index, in astronomy, the difference between two measurements of the magnitude (brightness on a logarithmic scale) of a star made at different wavelengths, the value found at the longer wavelength being subtracted from that found at the shorter.

What is the condition that results from B12 deficiency anemia?

Either a lack of vitamin B-12 or a lack of folate causes a type of anemia called megaloblastic anemia (pernicious anemia). With these types of anemia, the red blood cells don’t develop normally. They are very large. And they are shaped like an oval.

Can low B12 affect white blood cells?

Reduction in the number of white blood cells and platelets also can occur, especially when people have had vitamin deficiency anemia for a long time. The blood levels of vitamin B12 and folate are measured, and other tests may be done to determine the cause of the vitamin B12 deficiency.

What does Colour index indicate?

: a figure that represents the ratio of the amount of hemoglobin to the number of red cells in a given volume of blood and that is a measure of the normality of the hemoglobin content of the individual cells.
